JOHN KAIIIVODA, or CUBA, aims.

ROAD DRAG on scnarnn.

To all whom it may concern:

Be it known that I, JOHN KALrvoDA, a citizen of the United States, residing at Cuba, in the county of Republic and State of Kansas, have invented new and useful Improvements in Road Drags or Scrapers, of which the following is a specification.

This invention relates to road building apparatus, particularly to road scrapers or drags and has for its object the provision of an improved device of this character including a roller Whichis capable of being adjusted indifferent angular positions depending upon the nature of the road upon which the device is used, novel means being provided for effecting such adjustment.

Another object is the provision of a device of this character which is provided with a guide Wheel to the rear of which is mounted a reversible scraper blade held in position by specific adjusting means whereby its position may be varied when neces sary.

An additional object is the provision of a device of this character which will be simple and comparatively inexpensive in construction, easy to use, very eflicient in use, durable in service, and a general im provement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which Figure 1 is a plan view of the device, Figure 2 is a bottom plan View, Figure 3 is a side elevation,

Figure 4 is a cross section on the line IVIV of Figure 1, and

Figure 5 is a cross section on the line V-V of Figure 3.

Referring more particularly to the drawings, the numeral 10 designates a platform which is mounted upon a frame-work 11 formed preferably of angle iron of suit- Specification of Letters Patent.

place by suitable bolts 17 passing through selected ones of, holes 18 so that its position may be varied. The opposite frame bar 19 is formed with a longitudinal slot 20 through which pass bolts 21 holdin a bearing 22 whichis slidable along the underside of the bar '19. The numeral 23 desig-J nates an axle carrying wheels 24 and carrying between the side bars 15 and '19, a roller 25.

In order that the position of the roller 25 may be varied as required, I provide a toothed'segment 26 secured upon the frame bar 19 and having movable thereover' a pivoted lever 27, having a hand 28 operating a pawl ,29 engageable between teeth of the segment. By shifting thelever 27 in one direction or the other it will be observed that the bearing 22 may be slid along the bar 19 so as to vary the angular position of the roller 25.

Connected with the forward ends of the bars 15 and 19 are curved bars 30 having their forward ends provided with holes 30 adapted for engagement by any suitable draft device for pulling? the Whole mechanism over the ground. Secured to the forward end of the frame bar 19 is a segment 31 over which moves a lever 32 having a hand grip 33 controlling a pawl 34 cooperating with the segment 31. Connected with the lever 32 at its pivot point 35 1s a curved arm 36 which extends forwardly of the platform and which carries a guide roller 37 adapted to travel upon the ground.

i The numeral 38 designates a concavednut members 41 on the frame and provided at their upper ends with hand wheels 42, this structure permitting vertical adjustment of the bar 39 together with the blade 38. The slant of the blade forwardly or rearwardly is controlled by means of brace rods 43 connected with the bar 39 and slotted at their rear ends, as shown at 44,.

for the passage of securing bolts 45. In order to dig or cut ditches, I provide an auxiliary angularly disposed blade 46 sethe rollefr is to flatten and press doWnQt'he.
